大学生在双趋冲突和趋避冲突中的折扣率差异

The Difference of Discount Rate from Undergraduates between Approach-Approach Conflict and Approach-Avoidance Conflict

目的探讨大学生被试在双趋冲突和趋避冲突条件下的折扣率差异。方法让70名大学生完成两种条件下的延迟折扣任务(DDT)。结果趋避冲突条件下大学生被试的折扣率显著低于双趋冲突条件下的折扣率,在延迟奖赏为中幅度(50-60元)时折扣率最大。结论相对于双趋冲突,损益情况和延迟时间同时影响着被试在趋避冲突条件下的选择。

Objective To research the difference of discount rate when undergraduates made a choice under approach-approach conflict and approach-avoidance conflict.Methods Seventy undergraduates finished the Delay Discounting Task（DDT）under two conflict conditions.Results Subjects preferred a larger but more delayed reward under approach-avoidance conflict rather than under approach-approach conflict,the discount rate was the largest while delayed reward was between fifty Yuan and sixty Yuan.Conclusions Relative to the reaction of undergraduates under approach-approach conflict condition,both the results and delay time affected their decisions under the condition of approach-avoidance conflict.
